005 10.0 points Birds resting on high-voltage power lines are a common sight. The copper wire on which a bird stands is 2.78 cm in diameter and carries a current of 58 A If the bird's feet are 7.66 cm apart, what is the potential difference across its body? Copper's resistivity is 1.68 x 10 S2m. Answer in units of uV. 006 10.0 points A length of metal wire has a radius of 0.001 m and a resistance of 0.09...
You often see birds resting on power lines that carry currents of 52 A. The copper wire on which the bird stands has a radius of 1.7 cm. Assuming that the bird's feet are 4.5 cm apart, calculate the potential difference across its body.
Need help with these A current of 75.7 mA exists in a metal wire. How many electrons flow past a given cross-section of the wire in 9.4 min? The fundamental charge is 1.602 Times 10^-19 C. Birds resting on high-voltage power lines are a common sight. A certain copper power line carries a current of 122 A, and its resistance per unit length is 2.39 Times 10^-5 1 Ohm/m. If a bird is standing on this line with its feet...
A bird rests on a high voltage aerial power line with the current 100A.The wire diameter is 20mm, and the bird feet are 10cm apart. What should be the resistivity of the wire material to produce potential difference 10V between bird feet? mΩ*m PLEASE the answer is not 0.314 or 0.00314 and it should be in mΩ*m unit
Compute the voltage drop along a 22-m length of household no. 14 copper wire (used in 15-A circuits). The wire has diameter 1.628 mm and carries a 12-Acurrent. The resistivity of copper is 1.68
Compute the voltage drop along a 24-m length of household no. 14 copper wire (used in 15-A circuits). The wire has diameter 1.628 mm and carries a 13-A current. The resistivity of copper is 1.68×10−8Ω⋅m.
An electric utility company supplies a customer's facility from the main power lines (effective voltage V0=150 V) with two copper wires. Each wire has diameter d=5.28 mm and length l=34.83 m. The customer load current is known to be I=191.5 A. What is the voltage V at the customer facility for the given load current?: V= ___ V. How much power P0 is delivered by the main lines?: P0= ___ kW. How much power P is received by the facility?:...
A typical overhead power line is bare wire at a high potential relative to ground. A local line receives power at 3300 V with respect to the ground; the delivered voltage is slightly less, due to resistance loss in the wire. The wire is 10 km long, carries a current of 60 A, and has a resistance (made small to limit power loss) of 2.5 Ω. 1) Approximately how much power is lost due to the resistance of the wire?...
Part 1 Before we can consider the effects it might have, we must consider the high tension power line itself. Such wires are frequently constructed by twisting aluminum or copper wires together into a large flexible bundle. Consider such a copper cable with a diameter of 4 cm. If this cable is 10 km long, what is its resistance? Remember: Resistance = Resistivity * Length / Area Resistivity of copper is 0.0000000168 Ω-m Cross sectional Area of...
